CHUCK FO R PAPER-BOX-COVE R ING MACHINES.

SPECIFICATION forming part of Letters Patent No. 522,338,, dated July 3,1894.

, Application filed April 1394:-

To all whom it may conccrm- 3e it known that I, ISIDOR DREYFUSS, aCltlZGll of the United States, residing in the city, county, and Stateof New York, have invented certain newanduseful Improvementsin Chucksfor Paper-Box-Cover-in g Machines, of which the following is aspecification.

This invention relates to improvements-in chucks for holding paper boxeswhile the sides of the same are being covered with paper.

The object of myin vention is to provide a chuck of this kind, which canbe readily adusted for boxes of various sizes, and the sev eral parts ofwhich can be readily locked in place after having been so adjusted.

The invention consists in the combination of a central body having acentral tube, said body being provided with crossing grooves,cross-pieces at both ends and sides of the body, bars projecting fromthe cross-pieces through grooves in the body, loose sleeves on the tubeprovided with means for engaging said bars for permitting the twoend-pieces to be moved toward or from the ends of the box simultaneouslyand for permitting the s de-pieces to be moved toward or from the sideof the body and means for clamping said sleeves together.

The invention further consists in'the comblnation with the above parts,of plates secured to the cross-pieces and angle or cornerpleces mountedto slide on said plates.

The invention also consists of the construction and combination of partsand details as will be fully described hereinafter and finally pointedout in the claims.

In the accompanying d'rawings,'-Figure 1 1s a perspective view of myimproved chuck for paper box covering machines. Fig. 2 is a horizontalsectional View of the same on a reduced scale on line 2, 2, of 'Fig. 4.Fig. 3 is a plan view. Fig. l is a longitudinal sectional view on line3+3 of Fig. 3, parts being omitted. Fig. 5 is a horizontal sectional vieof the modified construction.

Similar letters of reference indicate corresponding parts.

Two blocks A and B are placed one above the other and are connected byscrew-bolts C passing through them, and provided with suitable nuts.

A tube D is passed through the two blocks,

Serial no. 606.296. (No model.)

I the upper end of saidtube projecting beyond the upper surface of theupperblock and having its projecting end screw-threaded externa'lly andon said threaded end the wingednut E is screwed;

' Two sleeves F and G surround the tube vD loosely, the lower sleeveFresting on the bottom external flange D of the tube D, which flange D iscountersunk in the under side of the lower block B, the sleeve Fextending to the upper surface of the lower block. The sleeve G restswithits lower edge on the upper edge of the sleeve F and said uppersleeve G extends to the upper surface-of the screwed down, bears on theupper end of said upper sleeve G. On the sleeves F and G the pinions Fand G respectively are formed.

The pinion F engages two racks H mounted to slide in grooves H in theupper surface of the lower block, which racks are provided at theirouter ends with cross-pieces J, which cross-pieces are at thetwo ends ofthe blocks. The pinion G engages two racks K arranged to slide ingrooves K formed in' the under side of the upper block A, and said racksK are provided at theirouter ends with cross-pieces L at the two sidesof the blocks.

gles with the grooves K. Metal platesM are secured to the outer faces ofthe cross-pieces J and L and on the same, the angle or cornerplates Nare mounted to slide, which angleplates have their upper andlower edgesbent inward andover the edges of said plates M, so as to permit ofshifting the angle or corner-plates toward or from eachother'on theplates- M according to the size of the box.

Pockets P are formed on the inner sides of the angle or corner-plates Nat the corners, and serve to receive extensionq'ods Q, which can belocked in place by means of screws R. Said extension-rods Q are used incase the height of the box is greater than the height of the plates Mand N.

In the modificationshown in 5, the

which are connected by links (1 with a cross- D and other cross-piecesfor the two sides are arranged in substantially the same manner,

so that .whena cross-piece at one end of the upper block A, so that thewinged-nut E, when.

" The grooves H are arranged at right-anpiece f mounted to turn on thecentral tube.

cross-pieces a are formed on the ends of bars I),

block is pushed in or out, the opposite crosspicce will be movedcorrespondingly and the cross-pieces at the side can be moved in likemanner.

The chuck is adjusted and used in the following manner: The winged-nut Eis loosened and the cross-pieces at the sides and ends are pulled outuntil a frame is formed by the plates M and angle or corner-pieces N, ofsufficient size to fill the box and then the parts are locked inposition by screwing down the winged-nut E. The extension-rods Q areinserted in case of boxes having greater height than the plates M. Thechuck having been adjusted to the proper size, is mounted on a spindleor pin, so as to turn with the same, which pin or spindle is rotated bymeans of any suitable mechanism. The box to be covered is then placed onthe chuck, one end of the strip of paper covered with paste or gum isapplied on one side of the box and as the box with the chuck continuesto rotate, the strip is successively applied on the four sides, the boxis removed, another one placed on the chuck, and so on.

The chuck can readily be adjusted in size for boxes that are narrow andlong, or square, and to varioussizes in the diiferent directions, allthat is necessary being to loosen the winged-nut E and then push in orout the sides or ends and then look the parts in place.

Having thus described my invention, I

, claim as new and desire to secure by Letters Patent-- 1. A paper-boxholding chuck, composed of a central body having a central tube,crosspieces on both ends and sides of said body, bars projecting fromthe cross-pieces through grooves in the body, loose sleeves on the tubeprovided with means for engaging said bars for permitting the twoend-pieces to be moved toward or from the ends of the box simultaneouslyand also for permitting the side-pieces to be moved toward or from theside of the box simultaneously, and means for clamping said sleevestogether, substantially as set forth.

2. The combination, with a central body having two sets of groovescrossing each other at right-angles, a tube at the center of the bodyand having its upper end threaded, two pinions mounted to turn on saidtube, two

the threaded upper end of the central tube and serving to bear on thepinions and lock them in place, substantially as set forth.

3. In a paper box chuck, the combination with a central block, of asliding-bar projecting from each side and eachend, means for causing thesliding bars projecting from the ends to move simultaneously, means forcausing the bars projecting from the sides to move simultaneously,crosspieces on the outer ends of said sliding-bars, plates secured tosaid cross-pieces, and angle or corner pieces mounted to slide on saidplates, substantially as set forth.

4. In a paper box chuck, the combination with a central block, of asliding-bar projecting from each side and each end, means for causingthe sliding bars projecting from the ends to move simultaneously, meansfor causing the sliding'bars projecting from the sides to movesimultaneously, cross-pieces on the outer ends of said sliding-bars,plates secured to said cross-pieces, angle or corner pieces mounted toslide on said plates, which angleplates have their edges bent over theedges of said plates, to form guides, substantially as set forth.

5. In a paper box holding chuck, the combination with a central body, ofa sliding-bar projecting from each end and each side, means for movingthe sliding-bars projecting from the ends simultaneously, means formoving the bars projecting from the sides simultaneously, cross-pieceson the outer ends of said bars, plates secured to said cross-pieces,corner or angle-pieces mounted to slide on said plates, and pocketsformed on the corners of said corner-pieces at the inner sides forreceiving extension-pieces, substantially as set forth.

In testimony that I claim the foregoing as my invention I have signed myname in proseuce of two subscribing witnesses.

ISIDOR DREYFUSS.
